In 2005, Renault left the Super Racing Weekend and started the World Series by Renault and the Formula Renault 3.5 Series, merging both the World Series by Nissan (whose engine contract had finished) and Renault V6 Eurocup. The Dallara chassis was retained, while the Renault V6 was improved to 425 PS. Formula Renault 2.0 Eurocup and the Eurocup Mégane Trophy also joined the series in 2005 to support the main FR3.5 series.

At the end of July 2015, Renault Sport announced it would be withdrawing its backing to the Formula Renault 3.5 from 2016 onwards, handing the control of the series to co-organiser RPM. However, Renault Sport also said it would continue the Renault Sport Series with the Renault Sport Trophy and the Formula Renault 2.0 Eurocup.[2]
